Final answer:
Four ways to vary the volume and intensity of exercise are: increasing weight lifted, decreasing rest time between sets, adding more repetitions, and altering the target.
Step-by-step explanation:
There are several ways to vary the volume and intensity of exercise:
- Increase weight lifted: By increasing the amount of weight you lift, you challenge your muscles more and increase the intensity of the exercise.
- Decrease rest time between sets: Shortening the rest periods between sets forces your muscles to work harder and increases the intensity of the workout.
- Add more repetitions: Performing more repetitions of an exercise increases the volume of the workout and can help improve muscle endurance.
- Alter the target: Changing the exercises you perform or targeting different muscle groups can vary the volume and intensity of the workout.
